Arknights is too real, right?

In the following days, Xia Feng gradually understood the basic information about this world.

【Red Asian United Nations】

The Sky Federation, composed of 13 countries, has a total of 221 large sky islands and 436 medium-sized sky islands. Each sky island has an average of 20,000 to 60,000 residents.

The entire Red Asia United Nations is located in the eastern sky of the world, and consists of hundreds of sky islands forming an interconnected sky country.

There are four huge [Eternal Lighthouses] erected on the ground corresponding to the connecting range of all the sky islands. In a sense, this kind of lighthouse is the guarantee for the survival of the United Nations.

This huge lighthouse is the crystallization of technology. It can provide the important natural environment required by the sky island, such as simulating sunlight, regulating temperature, blocking harmful substances, and even changing the changes of the seasons.

All empty islands must enter the radiation range of the lighthouse before they can settle down.

In other words, if the [Eternal Lighthouse] goes out, it will cause a devastating catastrophe.

However, according to Lu Yu, the lighthouse will not go out because the energy it requires is inexhaustible in the land below.

As for why people leave the earth and fly to settle in the sky, the reason is precisely because of this energy.

One day about 100 years ago, violent earthquakes occurred in many places around the world at the same time.

This kind of strong earthquake, which had no warning and was not even predicted by any scientific instrument, caused a devastating blow to countries around the world, including industry, production, transportation, communications, farming, etc.

In the face of this force majeure natural disaster, although the losses were heavy, there was nothing we could do. Soon, countries around the world invested in large-scale post-disaster reconstruction.

However, at this time, a famous geologist discovered a small change that occurred almost simultaneously in the world's land after a major earthquake.

After the earthquake, a new mysterious ore was crazily produced by some special force that didn't know where it came from.

After sampling and research, it was found that this special ore contains huge amounts of energy and is a super energy substance that is far ahead of the world's current knowledge.

This huge discovery is almost a subversive leap for the technological era that is already in a highly developed civilization.

Soon, scientific research institutions around the world focused on this mysterious mineral and vigorously developed corresponding scientific and technological systems.

And this kind of ore was named source stone.

Over time, Source Stone has been used in almost every field.

But at the same time, the substances emitted by the Origin Stone in the air will also cause people who come into contact with it to suffer from a special disease.

The specific symptoms of patients include physical weakness and organ failure. As the disease worsens, crystals will gradually appear on the body surface.

Up to this point, countries around the world still have not realized the seriousness of the problem, because the benefits of the existence of this new energy far outweigh the disadvantages.

It was not until decades later that people gradually discovered that something was wrong.

There are more and more mysterious ores spawned by mysterious forces, just like a skin disease affecting the earth.

It only takes a few months to cover tens of thousands of kilometers.

In this crazy state, no matter how much countries around the world mine and consume, they are far from being able to maintain balance.

This is like someone who likes money and thinks that more money is better. But when you wake up one day, you suddenly find that you have so much money that it fills the entire house, the entire street, and the entire community. You can't even open the door to your home.

By then, you will be trapped to death with your favorite money.

In this way, the serious problem of disappearing living space was gradually exposed, and as long as the Originite Plague approached the city, the residents living there would be infected with the disease in large numbers, until the entire city was submerged by the crazy breeding of Originium.

On the surface, this situation can be said to be very pessimistic, but it has not yet reached the level of catastrophe.

Because of the huge benefits brought by this mysterious ore, the technological level of this world has reached unimaginable heights in decades of development.

At this point, the [Sky City Project] started.

Several decades later, the sky-island technology was finally fully mature, and people were freed from the shackles of the earth.

However, the world's total population has also dropped by 90% in the course of decades of race. Just by looking at this number, you can see what a tragic disaster this is.

In this way, the surviving elite humans flew into the sky, and except for a small part of the island, the entire land became uninhabitable.

Looking down from a high altitude, as far as the eye can see on the earth below, there are all dark yellow hideous crystals.

In the laboratory, after listening to Lu Yu's science popularization for him who had lost his memory, Xia Feng fell into deep thought.

Of course, this world view does not conflict strongly with him, he has no memory, so what is needed now is acceptance.

However, after listening to this entire historical development, he asked a question out of nowhere.

Lu Yu, can I ask a question?

sure.

You said that this mineral can cause people to suffer from a special disease, right?

That's right.

I want to know, can this disease be cured by existing medical technology?

For some reason, he seemed to be looking forward to this answer.

Then, Lu Yu’s relaxed voice came.

sure.

Can it be cured?

Yes, and you also have this disease now. We are considering whether to remove harmful substances from your body.

As time passed day by day, while living on an empty island, Xia Feng gradually accepted the basic information of this world.

A month later, his physical observation was completed and the results came out.

However, this result is somewhat special.

The conclusion about Xia Feng is that the mysterious substance in his body is almost consistent with a certain sample data in the record, and its name is, [Ancient Stone, Black and White Twins].

This can prove that he is the successor of [Black and White Twins].

It is precisely because of this state that his illness caused by the Origin Stone cannot be cured. In other words, if he is cured, the black and white twins will leave his body.

After seeking his own opinions, the No. 1 Sky Island Scientific Research Department decided not to touch on this issue for the time being.

At the same time, because of the special status of his successor, the Red Asian Federation Government extended a friendly olive branch to him.

100 years ago, the concept of ancient stones appeared almost at the same time as the source stone. For a civilization that advocates technology, this kind of extraordinary power form is very rare.

So his existence is special in a sense.

After several months of getting along with each other, the federal government felt that Xia Feng himself was a very easy-going person. In response, the federal government wanted to invite him to work in the special research team of Sky Island No. 1 as a researcher.

Although he knows nothing now and cannot remember anything, it is precisely because of this that he has special value.

This is true whether it is for the Red Asian Federation or himself.

This is a pretty good choice for Xia Feng who has nowhere to go.

In this way, he became an official citizen of the Red Asian Federation.
